I want to simulate duty cycle resistor based amplifier using HSPICE . transient analysis results are fine but unable to get AC response of circuit. Can anyone help?

do you have idea of HSPICE RF version? As i dont have access to CADENCE .AC analysis of switching circuits like switched capacitor filters or switched mode power supplies requires an analysis mode like PAC (periodic AC) or PSS (periodic steady state) provided by Cadence Spectre or POP (periodic operation point analysis) in SIMPLIS. HSPICE doesn't offer a similar mode as far as I'm aware of. HSPICE HBAC analysis works similar, but it's dedicated to sinuisodal carrier frequencies with harmonics rather than rectangular switching signals.
